PLAYER-GRAND PEDAL-ACTION.

Patented Oct. 12, 1909.

To all whom it may concern:

Be it known that we, Jns'rns HATTEMER and ARTHUR Konin, citizens of theUnited States, residing at lest New York, in the county of Hudson undState of New Jersey, have invented certain new and useful Improvenientein Player-Grand Pedal-Actions; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which .it npperteins to niako'anduse thesame.

This invention relates to pedal notions for player grund pianos, and hasfor en object to provide e )edel n'iechanism ada ted to be mountedwithin a l-yre disposed eneath a. grand piano in substantially theusualmanner. A further object of the invention is to pro- Yvide an improvedform of lyre adapted to contain pedals when folded and to present, whenclosed, the usual pedals found in the lyre of e grand piano.

lVith these and other objects in View, the invention comprises certainnovel constructions, combinations and arrangements of parts, as will behereinafter fully described and claimed.

In the drawings :#Fidgure 1 is zt View of the pedal mechanism in side.elevation with the` side of the lyre removed, showing the edel shown. infull lines und folded within the lyre in dotted lines. Fig 2 is e Viewof the lyre in front elevation with the closure opened and also showingthe pedals in front elevation opened.

Like characters of reference designate corresponding parts throughoutthe several views.

The body of e grand inno is shown conventionall at 10 depen( ing beneathwhich nre the si e wlls 11 and 12 of the lyre being formed in anyapproved manner, and with the rear side closed by n back 13, :ind thefront closed by a front 14 having e lower section or door 15, hinged at16. Upon the base 17 a frame 18 is hinged having feet 19 carried rigidlytherewith adaptedy tol rest' upon the floor when the traine 1S is inppened posltlon, as shown 1n full lines in Hg. 1.

4Upon the frame 18 pedals 20 and 21 are pivoted as by the hinges 22 and23, respectively. "Within the lyre box levers 24 and 25 are respectivelypivoted, as :it QG and Q7, und also respectively connected by ii-.ennsof links 28 and :29 with the pedals 2() and "21A At any approved orconvenient. position within the piano body, bellows 30 are mounted,preferably in pairs, und from such bellows links 31 and dependdownwardly through the bottom of the body and are, respectively,connected with bell crank levers 38 sind 34. The bell crank levers 33and 34 are, respectively, connected by means of A links 35 and 36 withthe levers 24 and 25.

It will be seen from. Fig. 1 that the frame 18 and the pedals 20 and 21pivoted thereon are capable of being folded upon the hinge 3T within thelyre box to the position shown in dotted lines, and that when so closedthe cover 15 may be closed downwardly upon its hinge to close the frontof such lyre box, leaving only the pedals 38 extending outwardlytherefrom connected with the'usual pedal rods 39.

It will be apparent that with the lyre box; given a fanciful design,itwill be scarcely noticeable from the lyres ordinarily employed beneathgrand pianos and upon which the ordinary pedals are fulcrumed,

nected with the pedals, bellows positioned to actuele pneumaticmechanism, levers mounted to operate the bellows, and llnks connectinthe first-mentioned levers with In testimony whereof we a our sigthesecon -mgntioned leviers. f d l natures 1n presence of two witnesses.
